Abstract: An improved educational calculator permits sequential display of equations as transformations are made to solve the equations.First simultaneous linear equations are entered, and each time an advance key is depressed, process equations, obtained by transforming the equations step by step to reach their answers, are successively displayed on a liquid-crystal display screen. Each time a return key is depressed, the process equations are successively displayed from the answers to the equations in a reverse manner. The problem-solving method is selected through the entry of a solution key among the addition and subtraction method, the substitution method and the equivalence method, which are learned in the junior high school. The sequential display mode of the process equations can be switched between the automatic sequential display and the display on the basis of each entry of the advance key and the return key.
